Greater Western Sydney coach Leon Cameron admits he didn’t believe a top-four finish was possible at the start of the season, but now the Giants have snared a double chance he believes they can win the flag.

GWS guaranteed themselves a top-four spot with a clinical 37-point win over North Melbourne at Etihad Stadium on Saturday night.

“To sit in the top four, I definitely didn’t think that that was going to happen, but as the momentum of the season has built you definitely change your beliefs and focus that you might be able to get there,” Cameron said.

“Absolutely (we can win the flag). The season is just full of surprises. I’m sure that West Coast is sitting there thinking they can win it, I think Adelaide will bounce back.

“I think anyone can win it and we’re sitting in the top four at the moment, which is fantastic.

“We get a double chance, where that takes us to, I believe that our players can go all the way. But in saying that, there’s a hell of a lot of work to do.”

The Giants’ 16th win of the season came from a mature performance against a team they’d never beaten before with a big prize on the line and Cameron was proud of the way they rose to the challenge.

GWS led by 11 points at halftime and looked in control of the contest for most of the second half against a team hell bent on performing well after a host of veterans, including much-loved midfielder Brent Harvey, were told their services were no longer required.

“This was a big game for us,” Cameron said.

“We knew the Kangaroos would be up for it with what happened through the week.

“We came down here and we wanted to see how we handled that pressure in an environment where there were going to be lots of Kangaroos supporters and the game was going to hot.

“I was really proud that the boys stood up.”

The Giants moved into third with the win but will drop back to fourth if Hawthorn beat Collingwood as expected on Sunday, setting up a local derby against ladder leaders Sydney in the first week of the finals.
